In this issue we answer your queries about water use:
Q: My water bills look too high. Is there a leak at my site?
A: The easiest way to test for leaks is to conduct a 'night use test'. You need to turn off all water using equipment and read the water meter after everyone has left the premises. The following morning, before everyone arrives, read the meter again. Compare the two readings, if there is a difference there is likely to be a leak (or a use of water you are not aware of).
Other methods of identifying leaks include examining all water using plant and supply pipework, listening for drips or flows of water, looking for lush vegetation or continuously boggy or damp areas (are these near any pipes?) and employing a leak detection service.
Q: Why should I care about cutting my company's water use?
A: Water is becoming an increasingly expensive resource with mains, sewerage and trade effluent charges rising. By using less water you company will save money twice on both water supply and wastewater disposal. However if you get your water from an alternative source such as borehole or river this is likely to be a finite source and therefore increased availability may also be expensive. Managing water more efficiently can prevent any potential site expansion being limited by the availability of water or the need for an increased water supply.
Q: What is a water balance and why would I want to do one?
A: A water balance is a numerical account used to show where water enters and leaves your business, and where it is used within the business. It typically contains information about the amount of water used by each main process.
A water balance helps you to:
- understand and manage water and effluent efficiently
- identify the areas with the greatest opportunity for cost savings
- detect leaks.
